  agb2002: White is a bishop and a knight down.

The first idea that comes to mind is ("Patzer sees check...") 13.Qh5+, trying to unpin the bishop and reorganize the pieces with tempo:

A) 13... Ke6 14.Re1+ Be5 15.Rxe5+ Kd6 (15... Qxe5 16.Qxe5+ Kf7 17.Qxh8 + -) 16.Qd1+ Kc6 17.Qd5+ Kb6 18.Qb5#.

B) 13... Ke7 14.Bg5 winning the queen for three pieces and followed by Nc3, Rae1 with a winning attack due to Black's lack of development.

C) 13... Kf8 14.Bh6+ Ke7 (14... Nxh6 15.Rxf6+ Ke7 16.Qxh6 + -) 15.Bg5 transposes to B.

D) 13... Kg7 14.Bh6+ Nxh6 (14... Qxh6 15.Q(R)xf7#) 15.Rxf6 Kxf6 16.Qxh6+ followed by Nc3 and Rf(e)1 with a winning attack.

E) 13... Qg6 14.Bxd6+

E.1) 14... Ke6 15.Qe5#.

E.2) 14... Ke8 15.Rf8#.

E.3) 14... Kg7 15.Bf8# (go figure a name for this mate...).

E.4) 14... Nf6 15.Rxf6+ Kxf6 16.Qe5+ Kf7 17.Qe7+ Kg8 18.Qf8#.

  beenthere240: Redundancy -- unknown theory is an oxymoron.
May-09-14  Peter Nemenyi: The "known theory" discussion highlights the odd fact that in chess, "theory" actually means "the tiniest and most specific details of practice".

  Once: Known theory ....

To a layman, a theory is an idea which has not yet been proved.

To a scientist, a theory is an explanation for nature which can included both verified theories and unverified hypotheses.

To a chess player, theory is that which is known or believed to be known. Book knowledge which you have remembered, as opposed to something which you have figured out for yourself.

Known theory can be an oxymoron for a chess player because theory is that which is known. Unless of course you don't know the theory in which case it becomes unknown theory.

I suppose it's another case of chess using words in ways that other things don't. When most other sports uses the word "tactics" they tend to mean long term plans which we would probably call a strategy.

May-09-14  john barleycorn: < tamar: We need to get Donald Rumsfeld in to settle this.>

He is still fully occupied with the epaulette issue.

May-09-14  morfishine: <john barleycorn> & <shivasuri4> Well, I was just trying to be funny. Taken literally, and using the definition of oxymoron as a self-contradictory statement, for example "Cruel kindness" or "to make haste slowly" or "Civil War" I was trying to show the contrast between what is "Known" and what is just a "theory", with the idea that what has graduated from "theory" and is now "Known" is no longer "theory" and so the term "Known Theory" is self contradictory and thus, makes no sense

I guess, it wasn't that funny


May-09-14  john barleycorn: <morfishine> "seriously funny" I assume :-)

May-09-14  Cheapo by the Dozen: I was stumped, not seeing an effective continuation against ... Kg7, since White is behind in material after winning the queen and at that point has few pieces left.

  LIFE Master AJ: <morf> I thought it was hilarious! (With a ____ like <JB>, this site could use more humor.)
May-09-14  devere: <Cheapo by the Dozen: I was stumped, not seeing an effective continuation against ... Kg7, since White is behind in material after winning the queen and at that point has few pieces left.>

Those few pieces are enough for a winning attack against the exposed Black King, since Black cannot mobilize his pieces for defense quickly enough.

Wherever the Black King goes, White plays Nc3 and forces checkmate.

May-09-14  TheBish: S Jensen vs F Urkedal, 2013

White to play (13.?) "Difficult"

White is down two pieces, so he (she?) sacrificed for this attack. I'm assuming White needs to win the queen (or mate) without giving up too much more material. I believe I've found a way to do that, after which White needs to quickly bring the remainder of his forces into the attack as quickly as possible for this to succeed.

13. Qh5+!

I had looked at 13. Be5? Bxe5 14. Qh5+ (or Qd5+) followed by 15. Rxf6, but in this line White pays too great a price (rook and bishop) to win her majesty. Now there are several variations to look at:

(A) 13...Ke6? 14. Re1+ Be5 and now 15. Bxe5 Q-any 16. Bxh8+ wins, but even stronger is 15. Rxe5+ Kd6 16. Re4+! Kc6 (Qxf4 17. Rxf4 prolongs the game but is lost) 17. Rc4+ Kb6 18. Qc5+ Ka6 19. Ra4#.

(B) 13...Ke7? 14. Bg5 wins the queen for a mere bishop, so material will be even, but with Black's king exposed White has all the winning chances.

(C) 13...Kf8 14. Bh6+! Ke7 (or Nxh6 15. Qxh6+ and 16. Qxf6 wins the queen for nothing) 15. Bg5 transposes to (B).

(D) 13...Kg7 14. Bh6+! Nxh6 (not Qxh6 15. Qf7#) 15. Rxf6 Kxf6 16. Qxh6+ and it appears that White will be able to bring in reinforcements (knight and rook) and do some damage before Black has time to organize an adequate defense.

(E) 13...Qg6 14. Bxd6+ Nf6 15. Rxf6+! Kxf6 16. Qe5+ Kf7 17. Qe7+ Kg8 18. Qf8#.

I think that covers all the bases. Now I can go back to my baseball game! (Giants vs. Dodgers, big rivalry.)

May-10-14  TheBish: Wow, just played the game and noticed that White missed 15. Rxf6+!

  An Englishman: Good Evening: I shall describe "known theory" as reiterating a repetitive tautological redundancy, and leave that as my final word.

Which is probably a good thing.

  takchess: Those who forget theory are doomed to repeat it.
Feb-04-21  Christoforus Polacco: I love Polerio-Muzio Gambit. I love that game. Full respect for Soren Jensen. A wise decision to max sharpened the game against a much stronger opponent.
